Hi , i m opening this thread due to i need know what is the opinon from other tuners for that tool .
I have it since it produced , but i do not trust it . In my opinon it has some issue with checksum correction to a lot protocol . Let me share some of my issues, BMW 320i-msd80 ecu read/write on bench , i read it ,make it nox off with swiftec solution write back car not start at all , same file correct checksum with winols start and run all fine . Other car-problem MB A45AMG MED17.2.2 ecu using obd option , make id get virtual file make my tune file write it back (super fast almost 40sec) car starts & stops. i restore to ori all fine . i use a friends Dimsport Genius same tune file car starts perfect . i have some other issues such as dq200 mqb read file on bench, tune file try to write incorect file size error,i even choose actual read file again file size error.Finnaly, i destroyed a cla45 amg tcu getrag VGS2-FDCTG2 after read full read , and try to write tune file after many atempts car lost comunication each time i flash a tune file ,hopefully it restored by writing back full back up. i contact mms helpdesk they told me it might be a checksum correction and they will check it,after some days they come back and send me 2 files for testing . i write first file car not start -lost comunication but this time i can not restore tcu with full backup read , after some talking i realize that the files they send me was only with map area and i write them to bootloader mode .brand new tcu from MB i replace it offcourse ,mms give me 1 more year subs for free .
